COUPLING CONDITION DETECTING DEVICE FOR SLIDE FASTENER ELEMENT ROWS CAPABLE OF DETECTING A DEVIATION IN COUPLING OF A PAIR OF RIGHT AND LEFT ELEMENT ROWS

摘要

PURPOSE: A coupling condition detecting device for slide fastener element rows is provided to effectively and securely detect a deviation in coupling of a pair of right and left element rows which are coupled with each other with a slider mounted while carrying a continuous slide fastener chain through various kinds of finish processing portions, thereby reducing finish processing cost and improving product yield. CONSTITUTION: The element coupling condition detecting device for slide fastener element rows which is disposed at a carrying path of a fastener chain(C) for detecting a coupling of right and left elements located adjacent an end of a space in the fastener chain where the elements are missing, wherein the device comprises: a chain stopping unit(12) for stopping transportation of the fastener chain at a detecting position of the right and left elements and a detecting portion(60) having a mechanical detecting units for detecting presence/absence of a deviation in coupling of the right and left elements when the fastener chain is stopped.
